Serial No. 406,798.

To all whom it may concern:

Be it known that I, (in/nuns S. STARR, a citizen of the United States, and resident of Elmira, in the county of (.lhemung and State of New York, have invented certain new and useful Improvements in Packers for Hay- Prcsses, of which the following, with reference to drawings, is a dcscri tion thereof.

My invention relates to tiat class of devices attached to hay presses, as assistant means to pack the hay in the chute of the press, previous to the final action of the press in making the bale of hay, the object wing to make an GIIQCtlVO and easily operated device, doing the work of the pressmcn in having to jump down upon and tramp the hay while filling the press chute, and roviding for convenient lateral withdrawa of the press bar of my invention, from within the mile of hay and press chute during the operation.

In the accompanying drawings I have shown an upright press with my invention attached thereto, but wish it understood that I do not confine myself in its use to this style of press, but that the same may he used in various styles of presses, and in various ways without departing from the spirit of my invention when used for the appointed purposes.

In the drawings Figure 1 is a perspective elevation of portions of a hay press with my complete invention attached thereto. Fig. is a view in elevation of a press with the cover and one of the doors at the top of the press open, and a portion of the front wall broken away, with parts of my packer attached to the press and having the hay pressed to the bottom and ready to be refilled again over the press bar, and from which position as shown the said press bar may be removed to the left, when the final action of the press may begin from the bottom upward with the press closed at the top for that pur ose. Fig. 3 is a sectional plan view of the ower part of one of the packer standards to more fully illustrate the locking mechanism for the rack bars. Fig. 4 is a view in elevated plane of the same, but with the cap plate of the standard removed. Fig. 5 is a side view with a broken cross section of the removable press bar.

Referring to the drawings 1 represents a box or standard having near its lower part a laterally extended base flange 2 by means of which it is bolted, with a like standard, in upright position about midway on each of the opposite top rails 3 of the frame of the press.

Running in a groove 4 on the inner side of these standards in longitudinal direction. and down into grooves 5 of the walls of the press inside, and covered over by the cap plates 6, are the rack plunger bars 7, these rack bars have notches 8 nearly throughout their length which shoulder at right angles into the bar, and. at their lower ends are bisected with a vertically directed slot 9 opening from the end of the bar, and in direction across the press from one bar to the other, thus fitted to rest on and over astride the tongue of a reverted T shaped press bar 10 running across under the ends of the rack bars 7. The ends of the said press bar 10 are notched to form shoulders 11 and 12 on its tongue portion at either end into which the rack bars are seated, and are thus held from springing inward. One end of the press bar tongue is extended slightly beyond its notched shoulder, and has a hole 13 through it for inserting a hay hook, or otherwise obtain hold to withdraw said press bar endwisc through the opening 14 through the side wall of the press.

Between laterally projecting bosses of the cap plate 6 and the standard 1 on the pin 15 is pivoted a lever 16 which passes through an 0 en portion 17 of the standard along side of t 1e rack bar and is extended into a handle of considerable length away from the standard, and has pivoted to it a downwardly hanging pawl 18 pivoted on a pin 19 fixed in the lever close to the rack bar, and into the notches of which the pawl is fitted to drive said rack plunger bars forcibly downward, as the lever is swun or operated.

A sprin 20 seated against the awl below its journal and back into a raise portion of the handle, serves to keep the pawl into proper engagement with the rack bar. To hold said pawl out of en agement, when it is desired to slide the rack )ars upward, I have provided that the point or free end of the pawl can be set to rest in the notch 21, in the ase flange 2 of the standard, under the weight of the handle lever to hold it there.

22 represents a catch or locking bolt fitted to slide in a groove 23 cut laterally in the standard, and to and from connection with the rack bar notches, under the action of a spring controlled lever 24 which is pivoted to i the extended part of the cap plate on a fixed bolt 25, and has its lower end connected by slot and pin 26 to the outer end of the locking bolt. Said lever :24 above its pivot is extended into a handle and has attached to it a spring 27 the lower end of which spring is so bred and stationed to the supporting top rail of the press, to draw on the lever, so it will play the locking bolt inward a little more than the distance of the depth of the notches in the rack bar, thus making the catch or locking bolt act automatically to travel from notch to notch of said bar and lock same in any downward position, but when the lever 24 is thrown so as to bring the spring to draw over on the inner side of its pivot, the catch bolt is thereby pulled outward and will so remain out of connection with the notches of l the rack bar.

'lhrough the side wall of the press to v. hich my invention may be attached I provide for a slot or opening 14 through which the press bar may be removed end wise from within the press and be again ready for use at the top in the fiollowing operation.

The press being iilled with hay as snugly as ossible, the little levers 24 are thrown to llold the catch bolt out, and the pawls 18 are swung out into their retaining notches under weight of the levers. The rack plunger bars are now lifted to the to of the press, and the press bar laid on the llay under them, the catch bolt is thrown inward by its lever, and the two hand levers 16 are jointly operated, forcing the press bar down by the little pawls springing into the notches of the rack bars,

until the press bar comes below the opening 14-. The press is new again iilled with bay to the top and the cover 28 is slid home under the top rails 3 of the press. The rack bars are now released of pressure and the press bar withdrawn, and the press levers at the bottom put in action which lifts the bottom ress board 29 upward confining the hay in a bale at the top where it may be wired and removed through the door 30 with the cover slid oil', when the process may again be re peated.

WV hat I claim as new and desire to secure by Letters Patent is:-

1. In a hay press, a packer consisting of grooved standards rack bars arranged to travel therein, means for actuating the rack bars, a press bar reinovably connected to the rack bars, and means provided for withdrmving the press bar outwardly through the side wall of the press.

2. In a hay press, a packer, comprising rack bars provided with notches means for holding and guiding the rack bars, and means for engaging the notches to drive the bars forward, a press bar removably connecting the rack bars, and means for permitting the press bar to be withdrawn out endwise from within the press.

3. In a hay press, hay packer standards having flanged bases adapted to be bolted to the press rails, notched bars working in the standards, a T press bar connecting the notched bars, means for engaging the shoulders of the notches to actuate the press bar and cooperating means to lock the bars as they are advanced into the press.

4. In a hay press, hay packer standards, notched bars held by the standards and having their lower ends slotted, aT shaped press bar seated in said slots, levers with pawls fixed in the standards for advancing the notched bars, and lever and spring operated locking bolts for said. notched bars, substantially as described.

5. In a hay packer for hay presses, a press bar arranged for pressing hay within the press, means for actuating said press bar to press the hay, an opening in the press wall through which said press bar may be withdrawn from within the press.
